Bio-inspired fabrication of superhydrophilic and underwater superoleophobic alumina membranes for highly efficient oil/water separation / Wenjin Zhou in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 18, N° 2 (03/2021)

Dopamine deposited on the surface of alumina membranes through immersion over time, and then crosslinking reaction occurred with polyethyleneimine (PEI), which was confirmed by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. It induced the modified layer coated on the membrane surface. Values of water contact angle of the modified alumina membranes were ~ 0° in air. Values of underwater oil contact angle reached 155°, which indicated it was superhydrophilic and underwater superoleophobic. More particles engendered with the increase in the reaction time with PEI, which induced the decrease in the pore sizes and permeation flux. All values of oil rejection were higher than 98.5%. No obvious deterioration of permeation flux could be found. The rejection hardly suffered a sharp decline over 800 min. It indicates that the modified layer can firmly stick to the alumina membranes. Therefore, the as-prepared alumina membrane is promising for practical oil/water separation.

Langues : Américain (ame) Catégories : Fluorescence Fluoropolymères Nanoparticules Nitrure de bore Le nitrure de bore est un composé chimique du bore et de l'azote, de formule chimique brute BN (nombre égal d'atomes de chaque élément). Le nitrure de bore est isoélectronique avec le carbone et, comme ce dernier, existe sous plusieurs formes polymorphiques, dont l'une est analogue au diamant et l'autre au graphite. La forme diamant est l'un des matériaux les plus durs connus et la forme graphite est un lubrifiant apprécié. De plus, ces deux polymorphes possèdent des propriétés d'absorption radar. Oléophobie Oligomères Polyméthacrylate de méthyle Le poly(méthacrylate de méthyle) (souvent abrégé en PMMA, de l'anglais Poly(methyl methacrylate)) est un polymère thermoplastique transparent obtenu par polyaddition dont le monomère est le méthacrylate de méthyle (MMA). Ce polymère est plus connu sous son premier nom commercial de Plexiglas (nom déposé), même si le leader global du PMMA est Altuglas International9 du groupe Arkema, sous le nom commercial Altuglas. Il est également vendu sous les noms commerciaux Lucite, Crystalite, Perspex ou Nudec. Revêtements organiques Traîtements de surface Index. décimale : 667.9 Revêtements et enduits Résumé : Fluoroalkyl end-capped vinyltrimethoxysilane oligomer [RF-(CH2CHSi(OMe)3)n-RF; n = 2, 3; RF = CF(CF3)OC3F7] undergoes sol–gel reactions in the presence of hexagonal boron nitride (h-BN) nanoparticles under alkaline or acidic conditions at room temperature to afford the corresponding fluorinated oligomeric silica/h-BN nanocomposites in good isolated yields (~ 80%), respectively. The fluorinated oligomeric silica/h-BN nanocomposites thus obtained were found to exhibit a good dispersibility toward the traditional organic media including water. These two kinds of fluorinated nanocomposites were applied to the surface modification of poly(methyl methacrylate) (PMMA). The fluorinated nanocomposites prepared under alkaline conditions can give not only a good oleophobic characteristic imparted by longer fluoroalkyl groups in the composites but also the higher fluorescent emission related to the presence of h-BN on the only surface side of the modified PMMA film. In contrast, the fluorinated nanocomposites prepared under acidic conditions can provide a good oleophobic characteristic and a higher fluorescent emission on both the surface and even on the reverse side of the PMMA film. Such unique controlled surface modification ability will be discussed by 29Si solid-state NMR spectra of these two types of the nanocomposites.

A facile and low-cost preparation of durable amphiphobic coatings with fluoride–silica@poly(methacrylic acid) hybrid nanocomposites / Zheng-Bai Zhao in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 14, N° 6 (11/2017)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 14, N° 6 (11/2017) . - p. 1369-1380 Titre : A facile and low-cost preparation of durable amphiphobic coatings with fluoride–silica@poly(methacrylic acid) hybrid nanocomposites Type de document : texte imprimé Auteurs : Zheng-Bai Zhao, Auteur ; Da-Ming Zhang, Auteur ; Li Tai, Auteur ; Peng-Fei Jiang, Auteur ; Yong Jiang, Auteur Année de publication : 2017 Article en page(s) : p. 1369-1380 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Amphiphobie Hydrophobie Matériaux hybrides Oléophobie Revêtements Index. décimale : 667.9 Revêtements et enduits Résumé : Poor robustness, high cost and complicated preparation are the main barriers to the large-scale industrial application of amphiphobic coatings. A facile and low-cost method to fabricate durable amphiphobic coatings is reported in this work. The coatings were composed of top and bottom paints. The top paint was prepared by the F–Si@PMAA hybrid nanocomposites dispersion. The hybrid nanocomposites with dual structure were prepared via the co-condensation reaction of tetraethoxysilane (TEOS) and 1H,1H,2H,2H-Perfluorodecyl triethoxysilane (HDFTES) on the surface of the presynthesized PMAA nanoparticles in ethanol dispersion. The bottom one was a type of inexpensive car refinishing paint. The resulting coatings could be sprayed onto different substrates. All the coated substrates exhibited good amphiphobicity with superhydrophobicity with the water contact angle greater than 150°, water roll-off angle less than 4°, and high oleophobicity with the oil contact angle greater than 130°. Moreover, all of the prepared coatings exhibited great robustness after water jetting, sand abrasion, and knife scratching. This method can be an effective strategy for fabricating amphiphobic surfaces for practical industrial applications.

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 15, N° 3 (05/2018) . - p. 611-621 Titre : Facile fabrication of robust superhydrophobic cotton fabrics modified by polysiloxane nanowires for oil/water separation Type de document : texte imprimé Auteurs : Bin Wang, Auteur ; Binghang Lei, Auteur ; Yuhao Tang, Auteur ; Dong Xiang, Auteur ; Hui Li, Auteur ; Qi Ma, Auteur ; Chunxia Zhao, Auteur ; Yuntao Li, Auteur Année de publication : 2018 Article en page(s) : p. 611-621 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Coton Le coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles). Hydrophobie Oléophobie Séparateurs d'eau et d'hydrocarbures Séparation (technologie) Silicones Les silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki). Systèmes auto-assemblés Textiles et tissus à usages techniques Index. décimale : 667.9 Revêtements et enduits Résumé : The removal of oil and organic pollutants from water is highly desired due to increasing industrial oil-contaminated wastewater, as well as frequent oil spill accidents. In this paper, superhydrophobic and superoleophilic fabrics were facilely fabricated for oil/water separation application via in situ growth of polysiloxane nanowires on cotton fabrics. The polysiloxane nanowires were immobilized on the cotton fabrics through a self-assembly process of alkylsilane on the microfibers of fabrics. The combination of the hierarchical structure and the low-surface-energy polysiloxane nanowires greatly contributed to the superhydrophobicity of the fabrics. Furthermore, the superhydrophobicity remained even after they were exposed to different chemicals for 72 h and strong ultraviolet irradiation and repeated abrasion, indicating excellent stability. More importantly, the as-prepared cotton fabrics were successfully used for separating various oil/water mixtures by a solely gravity-driven process with high separation efficiency and desirable durability. The cotton fabrics are commercially available, low-cost, and environmentally friendly materials, and thus such superhydrophobic and superoleophilic cotton fabrics could be very attractive for oil/water separation and oil spill cleanup when high flexibility, strength, and chemical resistance are taken into account.
